中科院国家空间科学中心孙辉先到深圳作天文讲座

2017-07-24 15:59:29   央广网

央广网深圳7月24日消息(记者 王铖 通讯员 叶嘉晖 )7月22日,空间探测专家孙辉先为深圳市民作了一场题为《月宫探秘》的天文讲座。该活动由深圳市气象局主办,深圳市国家气候观象台(深圳市天文台)承办。

孙辉先是中国科学院国家空间科学中心研究员,现担任中国探月工程(二期)副总设计师、中国科学院月球与深空探测总体部总工程师,长期从事空间综合电子技术和空间飞行器有效载荷及系统集成技术研究,参加过载人航天、探月工程等国家重大科技工程研制与工程管理,为我国的航天事业,特别是为有效载荷的研制、推动与发展作出了卓越贡献。

孙老师的讲座由月球的基本常识和未解之谜讲起,指出月球虽然是我们唯一的邻居,但我们对它的认知仍很有限,由此引出探测月球的重要性和必要性。人类探月的历程从上世纪60年底开始,几十年来已经有许多国家加入到探月的队伍中来,且获得了许多重要发现。我国的探月事业起步较晚,但是发展迅速,现处于世界领先水平,嫦娥探月工程已顺利完成了“绕”、“落”、”回”3个阶段的前两步。孙老师还讲到工作过程中遇到了不少困难,科学家们不畏艰辛攻克了无数技术难题,才取得了今天举世瞩目的成绩。讲座最后孙老师提到下一步计划发射的嫦娥五号将实现取样返回,这是一次高技术挑战,未来还会对火星及小行星进行探测等。我国航天及探月技术与美国相比仍存在着差距,科研人员需要继续前进,不断创新,才能实现中华民族的登月梦、强国梦。本次活动的组织方——深圳市天文台位于深圳市大鹏新区南澳街道西涌,是政府投资建设、全体市民共享的民生工程。天文台每月设立公众开放日,市民可以在网站和微信上预约参观,聆听专业的天文知识讲解。
